The video creation bounty is already closed, so what will be the next bounty? I don't think this campaign is successful because a lot of videos is not good.
The purposed of having IBC youtube campaign is to promote the name of Nucleus project sinced they are the main sponsor of the said conference. So probably, the project are still on going and under developed by the team. We just have to keep an eye on this because I'm sure there will be new updates coming for this project.
